In this study, we propose a blind digital signature (BDS) scheme based on the elliptic curve digital signature algorithm that increases the performance significantly. The security of our scheme is based on the difficulty of the elliptic curve discrete algorithm problem. Therefore, it offers much smaller key lengths for the desired security levels, along with much faster cryptographic processes, leading to fewer hardware and software requirements. According to our simulation results, the relative performance improvement of our proposed BDS scheme is up to 96% when compared with previously proposed schemes.

The privacy and utility are treated as a major factor in influencing the role of data privacy preservation in cloud environments. There exists a trade-off between these two factors, where one factor should compromise its functionality over the other. It is hence necessary to maintain both utility and privacy for a data offloaded or accessed across cloud computing environment. In this paper, we develop a utility privacy model that established utility using Deep Adaptive Clustering (DAC) and privacy using elliptic curve digital signature algorithm (ECDSA). The utility is performed using clustering of the input datasets using DAC and the privacy is maintained using ECDSA. The simulation is conducted on specific datasets to test the efficacy of the model and the results shows improved accuracy on clustering, and efficient privacy metrics than existing methods.

elliptic curve digital signature algorithm (ECDSA) is a public key cryptographic algorithm based on the hardness of the elliptic curve Discrete Logarithm Problem (ECDLP), it is used to ensure users' authentication, data integrity and transactions non-repudiation. However, its weakness is to derive the signer's private key in case he uses the same random number for to generate two signatures for two different messages. Firstly, in this paper we present the ECDSA and analyse its variants proposed in the ***, we propose a new improvement technique for ECDSA of Liao and Shen and ECDSA of Chande and Lee. We intend to do so by introducing the unknown parameters which are used in the verification of the signature. Our aim is to overcome the problem which has not been explained in ECDSA schemes of both Liao and Shen and Chande and Lee.

In recent years, with the explosive growth of information, incidents threatening information security such as significant information leaks and personal privacy attacks have been constantly emerging. Research on public key cryptography has become an effective means to ensure security. elliptic curve cryptography, due to its ability to provide higher security and lower computational complexity, has gradually become the mainstream asymmetric encryption method in public key encryption systems. Its corresponding elliptic curve digital signature algorithm (ECDSA) has also gradually become a mainstream digital signature scheme. However, ECDSA often faces issues such as private key leakage and reuse of random numbers, leading to security risks. Physical Unclonable Functions (PUFs) with real-time reading, unpredictability, and non-clonability characteristics can effectively address the security issues caused by private key storage. This paper proposes a True Random Number Generator (TRNG) based on PUFs to address the security issues of ECDSA. The TRNG has passed NIST tests. The system adopts the spec256k1 curve, and experiments show that the entire system consumes 6.33ms for a single signature operation and 6.43ms for a single verification operation at a clock frequency of 100MHz. The entire system is implemented on Xilinx Zynq-7000 FPGA.

The Gaussian normal bases (GNBs) recommended by the National Institute of Standards and Technology (NIST) for the five binary extension fields of the elliptic curve digital signature algorithm (ECDSA), are self-dual. Multiplication, is a complex, and critical, field operation for the hardware-oriented implementations of field inversion - an important operation in the elliptic curve based algorithms - in the GNB representation. This paper, introduces a novel construction for the bit-serial parallel-in-serial-out (BS-PISO) multiplication over the "NIST-like" fields, based on the Trace mapping. The new formulations, are presented for the first time in literature as far as we know, and provide a new and simple understanding of the Trace-based mathematical model behind such a BS-PISO multiplication. In addition, derivation of existing formulations for the PISO GNB field multiplication, based on the new Trace-based construction, is presented. A digit-serial most-significant-digit first PISO field multiplication architecture is constructed, based on the new Trace-based BS-PISO formulations, and the corresponding theoretical space and time complexities are derived and compared to other counterparts. Moreover, post synthesis space and time readings are reported, based on Application specific integrated circuit (ASIC) realizations, using the NANGate 45nm open cell libraries.

The elliptic curve cryptosystems are paid more and more attention because its key string is shorter and its security is better than other public cryptosystems. The digital signature system based on elliptic curve (ECDSA) is one of the main stream digital signature systems. In this paper, we describe our proposed architecture to implement the ECDSA in FPGAs circuit. This architecture is planned to reach high performance running in FPGAs circuit. Synthesis results and relevant performance comparisons with related works are presented.

Random numbers are fundamental to all aspects of data security. The strength of a security mechanism is directly proportional to the randomness of the numbers it uses. These numbers are provided by special algorithms called Random Number Generators (RNG). This paper describes a novel security approach on authentification schemes as a modification of ECDSA scheme. The modification is done by adding a key stream generator, W7, to the standard ECDSA in order to increase the process security and in turn the authentification protocol performances. An efficient hardware implementation of the elliptic curve digital signature scheme was captured using VHDL language. For the hardware implementation of the design, an FPGA device was used. The implementation results illustrate the hardware performances in terms of time computation and area occupation. The proposed ECDSA scheme is suitable to be a reliable and efficient for embedded devices with respect to security interests.

Securing the edge: privacy-preserving federated learning for insider threats in IoT networks

Insider threats in Internet of Things (IoT) networks pose significant risks, as compromised devices can misuse their privileges to cause substantial harm. Centralized methods for insider threat detection in IoT devices are critical for identifying and mitigating insider risks. User behavior, such as access patterns, login times and data transmission, is profiled using machine learning algorithms to detect deviations that may indicate insider risks. However, training a model that generalizes across different data sources is challenging due to data heterogeneity, which can lead to a drift in performance. This paper introduces a decentralized approach called federated learning (FL) to address these challenges. An advanced privacy-preserving method is proposed for detecting and reducing insider threats in IoT devices. The process begins with a trust authority generating a random digital certificate using the hybrid Rivest-Shamir-Adleman and elliptic curve digital signature algorithm for IoT user registration. Node clustering is performed using the ordering points to identify the clustering structure with centroid refinement algorithm, ensuring data privacy by transmitting only cluster heads to local models. Additionally, the federated automatic weight optimization hash-based message authentication code with secure hash algorithm is introduced to further strengthen protection. The experimental results show accuracy rates of 98.85% on the simulated dataset and 83.74% on the X-IIoTID test dataset. These finding facilitates the effectiveness of the proposed solution in terms of accuracy, time, throughput, node scalability and overall performance. The results indicate that the proposed model outperforms other prominent approaches in the field.

A simple and rapid authentication protocol in mobile networks

Recently, mobile networks are more and more popular in providing the most pursuing pervasive networking services. Many technologies are deployed in mobile networks, such as Universal Mobile Telecommunication System (UMTS). In these communication systems, user secrecy and privacy are important issues and should be managed seriously. To avoid security threats, many studies on authentication in the mobile networks are proposed. In 2008, Juang and Wu introduced an authentication scheme with user privacy protection in UMTS networks. It resisted and avoided many security attacks and threats, but there are still some problems, such as the incomplete defense against the impersonation attack and data with International Mobile Subscriber Identity exchanged outside home networks. In this paper, we proposed a simple and rapid authentication scheme in mobile networks. The proposal applies the elliptic curve Diffie-Hellman key agreement protocol to exchange the session key safely and elliptic curve digital signature algorithm to improve the mobile security. It also deploys the temporary key mechanism to speed up the authentication while user is roaming in the mobile networks. The analysis shows that our mechanism not only improves Juang and Wu's proposal but also is a more secure and simple authentication protocol. Copyright (c) 2011 John Wiley & Sons, Ltd.

Booming telemedicine applications makes it deemed necessary to provide security services for such applications. The algorithms proposed in this field can be grouped into three classes: watermarking-based algorithms, crypto-based algorithms and hybrid algorithms. In this study, the authors propose two crypto-based algorithms capable of providing confidentiality, authenticity and integrity services to medical images exchanged in telemedicine applications. Strong cryptographic functions with internally generated symmetric keys and hash codes are used. The advanced encryption standard-Galois counter mode is used with the whirlpool hash function to provide confidentiality and authenticity, and the elliptic curve digital signature algorithm is used to provide authenticity and integrity. The proposed algorithms are based on the digital imaging and communication in medicine (DICOM) standard;however, unlike the standard, the algorithms provide confidentiality, authenticity and integrity for the header data, as well as for the pixel data of the DICOM images. Effectiveness of the proposed algorithms is evaluated and demonstrated through extensive experimentation using a benchmark set of DICOM images.
